Abstract

In addition to typical meadow species, Poa pratensis, 4 other species are recognized within this aggregate. Only the leaf width is used often for their identification. These species are known to be satisfactorily distinguished in their growth habits, but detailed studies showed that growth habit is not a reliable discriminator and it seems to be only a reflection of general trends. Neither width of leaves, nor characters of growth habit are successful features in their identification. To avoid wrong identifications, which could lead undesirable consequences, all morphological characters and growth habit should be simultaneously taken into consideration.
